Advice needed for cheap Graphics card for Optiplex 790 Small Form Factor

Hi all, I recently purchased an Optiplex 790 SFF with the intention of giving it to my nephew as a present.

I'm wondering a couple of things - What low-profile low cost graphics card would you recommend (support for 2 monitors) and would the 240V power supply be good enough to handle it?

If the power supply can't handle it, is there a more powerful small form factor option I could replace it with?

Cheers folks.

  1. The low-profile GTX750ti uses only 65W, that's the most powerful card that will fit. The rest of your system should be well under 100W. I would prefer you to have 300W psu, but....

    Thanks for this!

    I have a good 500W power supply in another case doing nothing, but the Optiplex looks awesome in my opinion. So yeah. I will install this, boost the ram to 8GB, add a 128GB SSD and a 1TB 3.5" drive and that should do it.
  3. I thnk the PSUs for those Optiplexes is a non-standard custom product and very difficult to replace.

    Yeah, you're right - they run down the inside of the case and are a long rectangular shape.
  6. The cards mentioned above and the one I suggested will all run off the PSU you have.

    Brilliant! Thanks mate!

    If I add more ram and a SSD will it tip the system into brown-outs on the 240W power supply?
  8. RAM and SSD will use no more than 10W at full power. It's the GPU that will be the main load.
